> Designs, drafts, and debugs working Erstan agents with you — every NetSuite write tool it wires stays approval-gated by contract.

**From a job description to a tested, running agent — designed before it is built.**

Most agent ideas die between the whiteboard and a working build: the trigger is wrong, the nodes don't match the job, or the first failed run never gets diagnosed. This expert builds Erstan agents with you, design-first. It clarifies the job to be done, surveys what you already have, picks the right trigger and node shape from the live node catalog, drafts the agent, inspects every node's wiring, and then reads real runs to diagnose and iterate. Any NetSuite write tool it wires into an agent keeps its approval gate — it never configures an agent to write without a human sign-off.

## Trust and governance

This agent is **read-only in NetSuite**: it queries and analyses your data but pins no NetSuite write tools, so it cannot create, change, or send anything on your behalf.

All activity is captured in a full audit trail, agents use your existing NetSuite roles and permissions, and your data is never used to train models.
